Optical and photoconductivity spectra of novel Ag 2In 2SiS 6 and Ag 2In 2GeS 6 chalcogenide crystals
(Elsevier B.V., 2012-06)
Complex spectral studies of near-band gap and photoconductive spectra for novel Ag 2In 2SiS 6 and Ag 2In 2GeS 6 single crystals are presented. The spectral dependences of photoconductivity clearly show an existence of ...

The studies of the dc-electric field induced second harmonic generation (SHG) for fundamental wavelength of the Ag2S–Ga2S3–P2S5 using nanosecond Er:glass laser at wavelength 1540 nm and elevated temperatures (thermal poling) ...
Single-crystal oxoborate (Pb 3O) 2(BO 3) 2WO 4: Growth and characterization
(Elsevier Ltd, 2012-09)
An oxoborate, (Pb 3O) 2(BO 3) 2WO 4, has been prepared by solid-state reaction methods below 620°C. Single-crystal XRD analysis shows that it crystallizes in the orthorhombic group Cmcm with a = 18.480(4) , b = 6.3567(13) ...
Shift of band gap from direct to indirect and optical response of lif under pressure
(World Scientific Publishing Co. Pte Ltd, 2013-04)
We hereby are reporting the transition pressure at which lithium fluoride (LiF) compound transforms from direct band gap to indirect band gap insulator on the basis of FP-LAPW calculations. The fundamental band gap of LiF ...
The influence of the lattice relaxation on the optical properties of GaNxAs1-x alloys
(Elsevier Ltd., 2013-04)
We have investigated the optical properties of the ternary alloys GaNxAs1-x (x=0.25, 0.5 and 0.75) without (we call it as case 1) and with (case 2) the lattice relaxation, using the full potential-linearized augmented plane ...
